SPI Serial Module

TEST-ARD-DIY-01

Published

SPI color display module demo page using minimal signal lines, suitable for resource-constrained embedded systems.(Standalone product 1)

Introduction

SPI interface saves MCU pins.
Supports partial refresh and common graphics drawing workflows.
Interface, parameters, and FAQ are all maintainable via backend.
Standalone product ID: 1.

Specifications

Specifications to be added.

Hardware

Core signals include SCK, MOSI, CS, DC, and RESET; backlight is independently controlled. Do not apply 5V directly to 3.3V signal pins.

Size

Connect power and SPI signals per the pinout table.
Configure chip select and orientation in the driver.
Run a solid color test first, then load the graphical UI.
Adjust SPI clock based on bus length.

FAQ

Why is the screen all white?: Check reset, chip select, data/command pins, and initialization model.
What if the image has noise?: Lower the SPI clock and shorten the connection wires.
